    Your stock tune is your base tune.

    Everything will be specific to your vehicle tuning wise. All airflow and fuel calculation are specific to the engine so you will need to tune it starting from stock.

    Grab yourself a wideband AFR gauge and start picking away at it.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Yeah, that would be your stock tune.

    It's not really possible to predict the fueling/airflow changes required for your specific engine. Nobody will have an exact plug and play data unfortunately. Starting the stock calibration is best.

    It will run and drive on a stock tune, that won't be an issue. It's the final details that you will be fixing. Start with getting your Primary VE and MAF curve in check. Then work on idle and timing adjustments and WOT fueling and timing last.

    Also if you are running factory 25lb/hr injectors you may not be able to do much at WOT, they may not have enough head room with the cam upgrade.

    The factory injectors ran out of fuel around 5400rpms with 241 heads targeting .85 lambda

    Hey Ben, do you mind sharing your file? i'm having some idle issues and i think it may help to see yours. i'm sure it'll be considerably different because im running different heads but still helpful. Whenever i goose it and let go in drive it dies or tries to when i lift my foot. not sure what the culprit is yet.

    Have the same set up and will be happy to share when I get it dialed in. Would also like to see others to learn and compare.
